The Tron blockchain has emerged as a powerful player in the decentralized finance (DeFi) space, offering fast transactions and incredibly low fees. One of the most popular platforms for swapping tokens on Tron is JustSwap, a leading decentralized exchange (DEX) built specifically for the ecosystem. Whether you're new to Tron or looking to deepen your DeFi knowledge, this comprehensive JustSwap tutorial will guide you step by step through swapping tokens, managing network resources, and adding custom tokens to your wallet.
What Is JustSwap?
JustSwap is the primary decentralized exchange on the Tron blockchain, functioning similarly to Uniswap on Ethereum or PancakeSwap on Binance Smart Chain. It enables users to swap TRC-20 tokens directly from their wallets without intermediaries. With growing liquidity and support for hundreds of projects, JustSwap has become a go-to platform for traders exploring opportunities in the Tron DeFi ecosystem.
Key features of JustSwap include:
- Instant token swaps with minimal slippage
- Liquidity pools with competitive APYs
- Built-in blockchain scanner for real-time transaction monitoring
- No traditional gas fees — thanks to Tron’s unique resource model

Understanding Tron’s Unique Fee Model: Bandwidth, Energy & Staking
Unlike Ethereum or other blockchains that charge variable gas fees, Tron uses a staking-based system to manage network usage. Instead of paying per transaction, users must hold or "freeze" TRX (Tron’s native token) to obtain two types of resources:
- Bandwidth: Required for basic transactions like sending TRX.
- Energy: Needed for interacting with smart contracts — such as swapping tokens or providing liquidity.
These resources regenerate over time or can be instantly replenished by freezing TRX. This innovative approach eliminates unpredictable gas costs, making micro-transactions and frequent trades far more affordable.
Pro Tip: If you plan to use JustSwap regularly, consider freezing a small amount of TRX to maintain a steady supply of energy and avoid delays during swaps.
Step-by-Step Guide: Swapping TRX for Another Token
Let’s walk through a real-world example — swapping 200 TRX for TRONPAD, a popular project within the Tron ecosystem.
1. Access JustSwap
Open justswap.io using a compatible wallet like TronLink or BitKeep. Ensure your wallet is connected and contains sufficient TRX balance.
2. Select Tokens
In the swap interface:
- Set TRX as the input token.
- Search for and select TRONPAD as the output token.
Enter the amount you’d like to swap — in this case, 200 TRX (approximately $15 at current rates).
3. Review Swap Details
You’ll see:
- Estimated output amount
- Price impact (usually minimal on well-liquid pools)
- Liquidity provider fee (typically 0.3%)
Notably, no gas fee is displayed — this is because Tron deducts energy instead of charging a direct fee.
4. Confirm the Transaction
Click “Swap” and confirm the transaction in your wallet. The smart contract will request a signature, but not a gas payment.
✅ Result: After confirmation, the swap completes almost instantly. In our test, 200 TRX was successfully exchanged for TRONPAD tokens with zero gas cost.
This efficiency highlights one of Tron’s biggest advantages: cost-effective DeFi interactions.

How to Add Custom Tokens to Your Wallet
After completing a swap, new tokens may not appear automatically in your wallet. You need to manually add them using the token’s contract address.
Steps to Add TRONPAD (or Any TRC-20 Token):
- Open your Tron wallet (e.g., TronLink).
- Navigate to the Assets section.
- Click "Add Token" or search for the token symbol.
- Enter the official contract address for TRONPAD.
- Confirm and add the token to your display.
Now, your TRONPAD balance will be visible alongside your TRX and other holdings.
Always verify contract addresses from official sources to avoid scams. Never trust links from unknown channels.
Exploring Additional Features on JustSwap
Beyond simple swaps, JustSwap offers several advanced tools that enhance user experience and earning potential.
🔹 Liquidity Pools
Users can provide liquidity to trading pairs and earn passive income through trading fees and reward incentives.
For example:
- TRX/TUSD Pool: Offers stable returns with low volatility.
- WBT/TRX Pool: Provides ~10.4% APY, paid in 6% WBT and 4.4% TRX.
Providing liquidity involves depositing equal values of both tokens in a pair. While it carries impermanent loss risk, it's a great way to earn yield if you’re already holding both assets.
🔹 Built-In Blockchain Scanner
JustSwap includes a native Tron blockchain scanner, allowing users to:
- Monitor live transactions
- Track pool liquidity and trading volume
- Analyze contract activity
This transparency helps traders make informed decisions without leaving the platform.
Frequently Asked Questions (FAQ)
Q: Do I need to pay gas fees when using JustSwap?
A: No. Tron doesn’t charge traditional gas fees. Instead, you need energy (obtained by freezing TRX) to execute smart contract actions like swaps.
Q: What happens if I don’t have enough energy?
A: You can freeze TRX in your wallet to generate energy instantly. Most of it can be unfrozen later when no longer needed.
Q: Is JustSwap safe to use?
A: Yes, JustSwap is a non-custodial platform — your funds remain in your control. However, always verify token contracts and beware of fake tokens with similar names.
Q: Can I lose money providing liquidity?
A: Yes, due to impermanent loss, especially in volatile pairs. It’s best suited for experienced users who understand market dynamics.
Q: How fast are transactions on JustSwap?
A: Transactions typically confirm within 1–3 seconds, thanks to Tron’s high-throughput architecture.
Q: Are all tokens on JustSwap trustworthy?
A: Not necessarily. JustSwap lists many community-launched tokens. Conduct due diligence before investing in low-cap or unknown projects.
Final Thoughts: Why JustSwap Stands Out
JustSwap exemplifies how thoughtful blockchain design can improve user experience. By eliminating unpredictable gas fees and enabling near-instant trades, it lowers the barrier to entry for everyday users exploring DeFi.
Whether you're swapping tokens for speculation, participating in liquidity mining, or simply experimenting with dApps, JustSwap provides a smooth, efficient gateway into the Tron ecosystem.
As decentralized finance continues to evolve, platforms like JustSwap demonstrate that scalability, affordability, and accessibility don’t have to come at the expense of security or functionality.
